In the 1949 Knesset elections he headed the Brit Hatzohar list, but it failed to cross the electoral threshold.
Although initially formed entirely by professional soldiers, with time it also included members of pre-war right wing Jewish-Polish parties such as Betar (among them Perec Laskier, Lowa Swerin, Paweł Frenkel, Merediks, Langleben and Rosenfeld), Hatzohar (Joel Białobrow, Dawid Wdowiński) (Political Chair), and the revisionist faction of the Polish Zionist Party (Leib "Leon" Rodal and Meir Klingbeil).
